Grok 4.8 Release Date: Preview and API Status

As of November 11, 2026, a general release date and public API access for Grok 4.8 remain unconfirmed in the sources checked. In a November 10 post, Elon Musk said pre-training is finished, reinforcement learning is running, and a Bot soft rollout was planned for later that week.

• Pre-training: confirmed by Musk's November 10 post.
• Reinforcement learning: running, with evaluations "starting to climb".
• Bot preview: planned for later that week; the post gives no start date.
• Public API: no Grok 4.8 entry in the model docs checked.
• General release: date unconfirmed.

Where Grok 4.8 stands on November 11

Three stages are easy to conflate: pre-training finished, a limited product preview, and a public model release. The November 10 post confirms the first and plans the second; it carries no timetable for API access or a general release.

Each row needs its own confirmation. A finished pre-training run is a training milestone, a Bot preview is a product test, and an API model arrives with an official model ID and access instructions. Musk's post reports completed pre-training and ongoing reinforcement learning, so the first two rows rest on that source.

A Bot preview reaching a few accounts would still leave the API row empty, and an API row can appear before a broad consumer release. Plan each stage separately.

What Musk said on November 10

Musk answered a user's timing question at 09:35 UTC on November 10. His post says the team dropped JAX and SGLang and rewrote the reinforcement-learning and inference stack in C/C++, which added time to the schedule. He then describes the current stage: pre-training done, SFT data cleanup mostly handled, and 4.8 in RL with evaluations climbing.

For availability he writes "soft rollout to Bot users later this week" and adds that the team will see how it goes. That is a plan for a limited audience, stated relative to November 10. The post leaves the calendar day open, gives no date for anyone outside that audience, and carries no API timing.

Musk also sets expectations: 4.8 will bear little resemblance to the previous generation, it is "not yet incredible", and he expects the foundations to carry it further. Read those lines as the author's own view of a model still in training.

Who gets the Bot preview?

The post names Bot users as the audience and gives no further criteria. Eligibility, supported countries, a sign-up path and how accounts are picked all remain unconfirmed, and the post names only Bot users. The rollout window is relative to November 10.

For teams planning around the preview, keep the API path separate: the preview is a product test, and API access is a separate step.

If you are choosing an assistant product this week, Claude Duet vs OpenAI Dots compares two Bot-style agents and the tasks each one suits.

Is there a Grok 4.8 API model ID or price?

xAI's model docs list Grok 4.7 as the flagship model for code and general work, and carry no Grok 4.8 model ID, price or entry. That page shows "Last updated: September 21, 2026", which makes it a directory snapshot from seven weeks before Musk's post.

So the model ID, price, context window, input types and rate limits for Grok 4.8 remain unconfirmed. A model can be tested privately while it stays off the public list, so wait for an official model ID and access instructions before changing a production config. Watch the models page and the release notes on docs.x.ai for a new row.

What would change this status?

Four signals below mark different stages, and each one covers only that stage:

1. A release-notes entry on docs.x.ai that names Grok 4.8.
2. A model row on the docs models page with an official model ID and access instructions.
3. A dated statement from xAI or Musk that the Bot rollout started.
4. A pricing entry, so you can estimate the cost of a request.

This snapshot reads Musk's post and the model directory on November 11, 2026, 15:49 UTC; we did not run Grok 4.8 ourselves, and x.ai's news and Bot pages returned HTTP 403 when checked.

Each stage stays unconfirmed until its own signal appears: a Bot rollout statement leaves the API row open, and an API row leaves consumer availability open.

What to use for real work now

For prompts you need to run today, Grok 4.7 is the model xAI's docs list as its flagship. OmniaKey carries it in the current model catalog, and the Grok 4.7 review covers its benchmark rows, API price and the checks for moving a 4.6 workflow across.

Keep a baseline this week: run a representative set of your existing tasks on Grok 4.7, save the outputs, and pin the model name in your config. When a Grok 4.8 row and official access instructions appear, rerun the same set before you switch production traffic. The same tasks make the later comparison fair, because a new training run changes behaviour on your work.

Frequently asked questions

Is Grok 4.8 out yet?

A general release date and public API access remain unconfirmed as of November 11, 2026. Musk's November 10 post puts 4.8 in reinforcement learning and plans a Bot soft rollout for later that week.

When is the Grok 4.8 release date?

No date is confirmed. The November 10 post gives a relative window for a Bot preview and no timetable for a general release.

Can I call Grok 4.8 through the API?

xAI's model docs checked November 11, 2026 list Grok 4.7 and no Grok 4.8 entry. Wait for an official model ID and access instructions before changing production config.

What is the Grok 4.8 model ID?

No official Grok 4.8 model ID appears in xAI's model docs. The page lists Grok 4.7 and no 4.8 entry.

Snapshot: November 11, 2026, 15:49 UTC. Update trigger: an official Grok 4.8 model ID and access instructions, a release-notes entry, or a dated rollout confirmation from xAI.
